City growth often time results in advancement and development in transportation which comes with its attendant changes in road infrastructure and transport support services such as road side mechanic workshops, vulcanizers and bus stops. A byproduct of these attendant contiguous activities and processes is the emission and release of trace heavy metals. Trace heavy metals have been identified as major carcinogens. This study aimed at determining the occurrence and concentration of heavy metals in roadside soils in an expanding third world metropolis. To achieve the aim of the research, the total length of the road within the study section was measured. Ten sample locations were indentified at about 2.5km intervals along the road section under review. The heavy metal concentration was determined the using Buck Scientific 210 VGP Atomic Absorption Spectrophotometer. Heavy metals such as Iron (Fe), Copper (Cu), Cadmium (Cd), Lead (Pb) and Mercury (Hg) were determined. The result of the analysis showed that the concentration values ranged from <0.001 to 48.90 µg/mg. The results also revealed that the experimental sample points recorded higher values than the control samples; however, some of the control points had relatively higher concentration values. This observation may have emanated from the low lying trajectory and topography of the surrounding area, which allows run-off from the road side soils to wash off heavy metals and deposit them at these lower lying areas. The sources of these trace heavy metals are attributed to emissions from motor vehicles that ply the road on a day to day basis. Emanating from the findings, this study recommends that improved public transportation and cleaner sources of energy is recommended.

The Road

Heavy metal concentration in roadside soil and plants are increasingly becoming of health concern. This work determined the concentration of selected heavy metals (Cd, Pb, Zn, Cr, Fe, Mg, Mn, Co, Ni and Cu) in roadside soils and plants samples from selected sites (Plaifu, Shiwa, Fadama-rake and Damdrai) along major road in Hong. Soil samples were taken 10 m, 20 m and 30 m away from the edge of the road at the  depth of 0-10 cm, 10-20 cm and 20-30 cm. Plant samples were randomly collected within the vicinity where the soil samples were taken and were analysed using Atomic Absorption Spectrophotometer. The result revealed the trend in soil heavy metal concentration was Fe > Mn > Mg > Pb > Zn > Ni > Co > Cu > Cr > Cd and for plant the trend was Fe > Mn > Mg > Zn > Pb > Ni > Cu > Cd > Co > Cr. The concentrations decreased with increasing distance away from the edge of the road as well as with depth at which the soil sample were taken. The transfer factor showed that the concentration of Zn, Mn, Cu and Mg were greater than 1, which shows that plant were enriched by Zn, Mn, Cu and Mg from the soil. Mg and Cd equal to 1 at Plaifu and Damdrai. Most of the values of TF at the study area super pass 0.5, which implies that generally, the ability of bioaccumulation of these heavy metals in examined plants were relatively high.

The Impact

Vehicles release large amounts of heavy metals to the environment. There have been done a lot of investigations analysing the distribution of heavy metals in soils near intensive regional roads. However, there is lack of investigations into the impact of small-intensity gravel roads on roadside soil contamination with heavy metals. The object of this investigation is four gravel roads of local significance connecting small villages. The intensity of these roads is very low. The gravel roads are chosen according to application of dust-minimizing materials, for example, CaCl2 and oil emulsion. According to our results, none of the soil samples had an excess of heavy metal concentration limit. Besides, heavy metal concentrations were decreasing with a distance from the road increasing. We can make an assumption that road dust-minimizing materials do not have a significant impact on heavy metal distribution in roadside soils. The major factors of heavy metal pollution distribution in roadside soils are traffic intensity, roadside trenches, and topographic conditions. Santrauka Eksploatuojant autotransportą, į aplinką patenka daug sunkiųjų metalų. Atlikta nemažai tyrimų sunkiųjų metalų paplitimuidirvožemyje šalia intensyvių magistralinių kelių nustatyti, tačiau mažo intensyvumo keliai šiuo požiūriu tiriami mažai.Tirti pasirinkta 4 žvyrkeliai – vietinės reikšmvs keliai, jungiantys nedideles gyvenvietes. Eismo intensyvumas šiuose keliuose mažas. Žvyrkeliai pasirinkti pagal taikomas priemones dulkėtumui mažinti, t. y. du nagrinvjami žvyrkeliai apdorotiCaCl2, kiti du – naftos emulsija. Nė viename mėginyje sunkiųjų metalų koncentracijos neviršijo DLK, o tolstant nuo važiuojamosios kelio dalies sunkiųjų metalų koncentracijos buvo mažesnės. Galima daryti prielaidą, kad kelio apdorojimo medžiagos dulkėtumui mažinti žymios įtakos sunkiųjų metalų pasiskirstymui pakelių dirvožemyje nedaro, lemia transporto srauto intensyvumas, kelio grioviai pakelėse bei reljefo sąlygos. Резюме При эксплуатации автомобилей в окружающую среду попадает много тяжелых металлов. Проведено немалоисследований, посвященных анализу распространения тяжелых металлов в почве обочин интенсивно эксплуатируемых магистральных дорог, однако исследований, касающихся аналогичных проблем дорог малой интенсивности, в настоящее время имеется немного. В настоящей работе в качестве объекта исследований выбраны четыредороги местного значения с гравийным покрытием, соединяющие небольшие поселения. Интенсивность дорог небольшая. Гравийные дороги выбраны с учетом их обработки для уменьшения пыльности – две дороги обработаны с применением CaCl2, а две другие – с применением нефтяной эмульсии. Ни в одной пробе не былозафиксировано концентраций тяжелых металлов, превышающих допустимые нормами. С удалением от проезжей части концентрации тяжелых металлов уменьшались. На основании исследований можно сделать вывод о том,что материалы, применявшиеся для уменьшения пыльности дорог, большого влияния на распространениетяжелых металлов в почве обочин дорог не оказывают. На распространение тяжелых металлов в почве обочин оказывает влияние интенсивность транспортного потока, кюветы на обочинах и условия рельефа.

Levels of lead, cadmium, and nickel in roadside soils and vegetables along a  major highway in Gazipur, Bangladesh were investigated. Soil samples were  collected at distances of 0, 50, 100, and 1000 m (meter) from the road. The  concentrations of lead (Pb) and nickel (Ni) in soil and vegetables (bottle gourd  and pumpkin) decreased with distance from the road, indicating their relation to  traffic and automotive emissions. The concentration of cadmium (Cd) was found  to be independent of distance from road. There were significant differences in  the concentrations of lead, cadmium, and nickel for different plant species and  soils at various distances. The heavy metals contents both in the soils and  vegetables for every distance from the road was found in the order  nickel>lead>cadmium. DOI: http://dx.doi.org/10.3329/bjar.v37i1.11170 Bangladesh J.

ABSTRAK Infrastruktur merupakan suatu pembangunan fasilitas berupa fisik maupun non fisik yang sengaja dibangun untuk menujang kebutuhan masyarakat baik itu secara sosial maupun perekonomian, salah satu bentuk dari infrastruktur adalah pembangunan jalan, di mana jalan itu juga identik dengan kemacetan khususnya pada wilayah kota-kota besar maupun daerah yang memiliki aktivitas penduduk yang cukup padat. Kawasan Tlogosari Semarang merupakan kawasan yang sering terjadi kemacetan, di karenakan para pengguna jalan lebih banyak menggunakan kendaraan pribadi daripada kendaraan umum, sehingga hal tersebut juga bisa memicu kemacetan karena jumlah kendaraann yang padat, ditambah lagi faktor-faktor lain yang menyebabkan kawasan ini sering macet terlebih pada jam berangkat dan pulang kerja.Identifikasi pada penelitian ini menggunakan metode penelitian kualitatif dengan hasil penelitian yang membuktikan terdapat tiga faktor utama kemacetan tersebut yakni karena wilayah Kawasan Tlogosari Semarang merupakan wilayah yang cukup strategis, sebagai salah satu pusat perdagangan dan jasa, serta merupakan kawasan pendidikan.Kata Kunci : Kemacetan, Kawasan, Jalan ABSTRACT Infrastructure is a construction of facilities in the form of physical and non-physical that is intentionally built to support the needs of the community both socially and economically, one form of infrastructure is road construction, where the road is also synonymous with congestion, especially in large cities and regions. which has a fairly dense population activity.The Tlogosari area of Semarang is an area that often gets traffic jams, because road users use private vehicles more than public transportation, so that it can also trigger congestion due to the dense number of vehicles, plus other factors that cause this area to often get jammed especially on the way to and from work.The identification in this study uses qualitative research methods with research results that prove there are three main factors of the congestion, namely because the Tlogosari area of Semarang is a strategic area, as a center of trade and services, and is an educational area.Keyword: Congestion, Area, Road

Studying the heavy metals in roadside soils is very important in evaluating the probable automobile emission’s environmental effects on the soil. To conduct the study, the soil samples were gathered and examined for the Pb, Zn, Mn, Cu, Ni, Cd, Co and Fe levels by the use of AAS. It was found that the order of the mean total metal content for the examined metals: Fe > Zn > Mn > Pb > Cd > Cu has a decreasing trend. Other than Cd, it was reported that all metals are lower compared to the levels of those found in other studies. Not involving Co and Ni shows that there is no pollution because of such metals. A correlation analysis was performed between metals and the traffic volume (V), indicating that there is a significant positive correlation (p < 0.05) between Pb, Cd and Mn, and V. In addition, the vehicular emissions are the main reason for originating the metal pollution in the soil for example motor vehicles. For this reason, the present study presents an applied approach to control the level of such metals.

Traffic activities are one of major sources leading to roadside soil contamination due to their long-term accumulation effect. The typical elements of Cd, Pb, Zn, and Cu in the roadside soil can transport through food chain to human body and result in a strong toxicity to people. In agricultural area, intake of heavy metals through the soil-crop system could play a predominant role on human exposure to environmental heavy metals. The study investigates concentrations and distributions of the four heavy metals’ in herbaceous plants growing in the roadside farmland around Kathmandu, Nepal. Totally, 60 plant samples including 26 samples from rural mountainous farmland and 34 samples from suburban farmland were collected from April 2011 to May 2011. The sampling distances to the road edge are 0 m, 10 m, 30 m, 50 m, and 100 m. The samples are classified into tree protection or no tree protection. It is found that the heavy metals’ distributions are not consistently decreasing as roadside distance; the heavy metal concentration in rural area is significantly lower than those in suburban area; and tree has a significant protection effect on roadside plants from the Cu contamination.

This study was conducted between February and September, 2018 to evaluate heavy metal concentrations of road dust soils supporting arable crop production along five major roads connecting the Umuahia Metropolis to surrounding cities. Thirty soil samples from five major roads were collected during the dry and wet seasons at 10 m, 20 m and 30 m distances from road edges. The heavy metals were analyzed using tri-acid digestion. The results showed that mean concentrations of the heavy metals varied widely and had significant different between the seasons, among the five major roads and usually, decreased with increased in distance from the road. Accordingly, the study indicates that, the relative sequence of abundance followed the order: Fe > Zn ≥ Pb > Cd > Cr ≥ Cu > Co > Ni > Se ≥ As. Higher content of the heavy metals was recorded during the dry season (83.94 mg kg-1) than the wet season (74.72 mg kg-1). Among the roads, higher content of the heavy metals was recorded in Uzoakoli road (105.50 mg kg-1) while, the least was recorded in Aba road (53.37 mg kg-1). Similarly, higher contents of the heavy metals were recorded within the distance of 10 meters (94.56 mg kg-1) while, the least was recorded in 30 meters (61.73 mg kg-1) away for the roadside. Since the roadside soils in Umuahia Metropolis are being extensively cultivated for agricultural production, proper biomonitoring of activities in the urban environment should be done as often as possible to enlighten the public on dangers of heavy metal pollution.

Heavy metals can be released into the aquatic environment through storm-water run-off and wastewater discharges and reprocessing from various industrial and anthropogenic activities. They have the potential to be toxic to biota above certain threshold concentrations while sediments in the marine ecosystems act as long-term sinks for many anthropogenic contaminants such as these organic pollutants. This study was therefore aimed at determining the heavy metal contents in the surface water, sediments and fishes from the Bodo/Bonny river. Sampling was done according to standard protocols. Surface water, sediment and fish samples were collected from 5 stations (BBW1, BBW2, BBW3, BBW4 and LFPW5) with LFPW5 serving as control.  Sediment was collected from 0-15 and 15-30 cm. The fish gills, liver, kidney etc. were excised from the rib for heavy metals (Pb, Fe, Zn, Cr, Cd etc) analysis using sterile scalpel. The results of heavy metal in surface water samples show that Zinc had a range of 173.1±10.21 to 179.3±11.01 mg/kg in all sampling locations above the permissible limit of DPR limit of 5 mg/kg for Brackish/ Saline water.  The sediment samples were loamy. The concentrations of trace metals in sediments revealed that Pb had the highest concentration of 48.61mg/kg at 0-15cm depth while Chromium had highest concentration of 41.54mg/kg at 15-30cm depth. Chromium, Cadmium and Copper increased with increase in depth at 15-30cm while Lead, Zinc and Iron took the reverse trend at 0-15cm depth. Heavy metal content of fish samples from the  river water show that the mean concentration values in the fresh fish was in the increasing order of Copper < Cadmium < Nickel < Lead <Iron< Zinc. The data generated from this study showed that there were actually heavy metals accumulations in fish tissues that were above the WHO permissible limits. The increased heavy metals concentration from all sites suggest that fishes that inhabit polluted areas risk bioaccumulation, which go on to affect the overall health of the human population that depend on such rivers for fishing, drinking or irrigation.

In this work x-ray fluorescence(XRF) technology was used to evaluate the soil pollution with heavy metals (K, Ti, Cr, Mn, Fe, Cu, Zr) in rain run-off deposited metal sediment of road side soil in Ado Ekiti, Nigeria. The investigated sediment of road side was collected in open places along the road at different districts in Ado Ekiti. XRF was carried out at the laboratory of Obafemi Awolowo University centre for energy research using handheld thermo scientific energy-dispersive XRF analyzer. The experimental result indicate that the concentration of heavy elements in Adebayo road is the highest level detected while the road at new Iyin road is lowest and they are greater than the level detected in a control soil collected from a zone situated far from the road. For the majority of metals, pronounced maximum, concentrations were detected in the site. Anthropogenic releases give rise to highest concentrations of the metals relative to the normal background values and in some locations their levels exceed the alert level admitted by the Nigeria guideline.
